To all whom it may concern: I

Be it known that I, PALMER O. Mnnais, a citizen of the United States, residing at Fer- ;ijus Falls. in the county of Otter Tail and Qtate of Minnesota, have invented certain new and useful Improvements in :1 Heater for Automobiles, of which the following is a specification.

My invent-ion relates to a heater for automobiles.

An object of my invention is to provide n heater for automobiles, that will utilize heat from the exhaust pipes of an internal combustion engine, to preheat the intake mixture.

A further object of my invention is to provide an attachment for automobiles; which may weather.

A still further object of my invention is to provide a heater for automobiles, that may be readily mounted on any well known form of internal combustion engine, "and which may readily be detached when it is desired.

A still further-object of my invention is to provide a heater, for automobiles, which may) be formed from a single strip of materi l.

A still further object of my invention is to provide a heater for automobiles, which is; strong, durable, simple and inexpensive in construction, and which is well adapted to the use for which it is designed.

Other objects and advantages of the invention will become apparent during' the course of the following description.

In the accompanying drawings, forming a part of the specification and in which like numerals are employed to designate like parts through the same.

Figure l. is a perspective view illustrating my in veution applied to an internal combustion engine.

be used as a heater in cold.

in, Figure 9.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 representsany well known form or type of internal combustion engine, as is ordinarily used in an automobile. The numeral 6 represents the carbureter having the intake manifoid .7 and the air pipe 8. The strip of materiel from which my invention is formed, is designated by the numeral 9 in its entirety. Formed in the plate 9 are large openings 10 for the branches of the exhaust manifold to pass through. The smaller openings 11 areformed for the bolts in the motor to pass through to hold the same securely in place when in use. The openings 12 around the outer edge of the plate 9 are made to allow bolts to he passed through the same, to hold the same when it is bent into-shape as is illustrated in Figure 1. Irregular portions 13 are cut outof the stripes is illustrated to allow the pipe 8 to pass through my heater, as is clearly shown in Figure 1 at point 14.

\Vhen the strip 9 is formed as is shown in Figure Lan opening 15 is formed by reason of the cutout portions 16 shown in Figure 9.. This opening 15 is opened or closed by means of a valve member 17, said valve member 17 being provided with the arms 18 which protrude through the openings 19. Any form (it-control mechanism may be attached to one of the arms 18 so as to raise or lower the valve member 17. The strip 9 is provided with aslit 20 so that when it is termed into a heater as is shown in Figure l. the same will not buckle.

in use a strip of material is first cut out as is clearly illustrated in the drawings in Figure 2, theposition of the various openings and cutout portions being governed by the type of motor to which the heater is to be used. The nix'essary bolts in the motor are removed andlikowise the manifold is removed. The manifold branches. are put through the openings 10 and connected to the motor again, and the bolts are inserted through the openings 11 and put into place. It will thus be seen that my device is firmly held into position, and cannot possibly become dislodged. until the bolts are removed. One of the features of this heater is the simple valve member 17 mounted at the rear end of my device. For instance, if it is in the summertime and it is not desired for the interior of the automobile body tobe heated,

into the front end of my heater through my.

device, being heated by reason of the exhaust- .munii'old, and will. pass through the rear opening end of the device into the interior ot' the car, thereby warming the feet of the occupants. It will be seen that I have devised an efficient device, whereby the gaso line may be preheated so as to vaporize the same and also have utilized the heat thrown oil from the exhaust manifold, to warm the interior of an automobile.

It is to be understood that the form of my invention herewith shown and described, is to be taken as the preferred embodiment of the same, but that changes in details may be made providing the same do not depart from the spirit of my invention or the scope of the subjoined claims.

ing inner and outer side walls of substantially the same size and shape to receive th branches of exhaust manifold of an internal combusl ion engine, the inner wall being provided with openings to receive the branches of the manifold, means for holding the body on the nmnit'old, inwardly directed overlapping flanges formed on the side Walls of the body at the rear end of the body, said side walls being provided with alined openings and means cooperating with said openings for permitting the control oi the flow of heat and air through said body.

In testimony whereof I aflix my signature.
